What causes blood sugar to drop too low right after a meal?

High glycemic index: Foods (sugars, rice/white bread/potatoes/pasta) can rapidly raise blood sugar & trigger large release of Insulin which overcompensates & drops the blood sugar low. Mix good fats & protein with your meals & cut back on the sugars/starches should help stabilize blood sugars. See doc to be tested for "pre-diabetes" especially if diabetes runs in your family or your are significantly overweight. ...Read more

The body naturally tightly regulates blood glucose levels as a part of metabolic homeostasis. Glucose is the primary source of energy for the body's cells, and blood lipids (in the form of fats and oils) are primarily ...Read more

Hypoglycemic: Normal blood sugar 1 to 2hours after a meal in non-diabetics is below 100mg/dl. The range is considered to be between 70 and 100. If yours falls below this you are considered to be in the hypoglycemic range but in as much as your are not on medications to lower your blood sugar or have a condition that will do this, or it continues to drop,it is not dangerous. If you have symptoms, see a doctor. ...Read more

No immediate worry: Eating a large load of carbohyderates and sugary drinks causes the body to produce excess of Insulin which can lower the blood sugar excessively(It is called reactive Hypoglycemia). It is not uncommon in the general population and can be avoided easily by limiting sweet drinks or avaoiding them alltogether. Another option is to add more proteins to your meals....this will slow down insulin release ...Read more

IFG: Hi. You have impaired fasting glucose (IFG) but mount a brisk insulin response to a caloric load. You're early in the type 2 diabetes process, probably in the "prediabetes" stage (you ARE prediabetic by IFG). Healthy diet & exercise should be your lifelong lifestyle. There are medicines that help prevent progression to type 2 diabetes as well. Talk with your doc. Good luck! ...Read more

1 hour after a meal and my blood sugar is 16.9 mmol is this bad???

Not normal: Hi. Finger stick capillary blood glucose is not approved for diagnosis. However, having said that, that's an awfully high blood glucose for 1 hour after a meal. I suggest you get a fasting SERUM glucose and an A1c at the least; a serum glucose 2 hours after a 75 gram oral glucose load is a good idea too. I bet you'll find multiple abnormalities. Eat healthily and exercise regularly. Control diabet ...Read more

What is the normal range for blood sugar 3 hours after a meal (dinner)?

Depends: It depends on what you ate for dinner and what was your carbohydrate intake in the previous 3 days. There are not "normal" figures for the circumstance you described, however, if your blood sugar was higher than 140, it would be prudent to consult a doctor for fasting blood sugar and if needed, a glucose tolerance test. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex, if you have sex. ...Read more

The : The most important point to stress here is when the blood sugar is taken after a meal. Two hours after a meal is a true measure of how well your body is allowing the sugar you consumed to be taken up by the cells( role of insulin). If you take it around an hour after, that is merely an indication of how much sugar you ingested at the meal and does not really tell us much. Therefore the two hour is what will give you useful information. If your boyfriend has well controlled diabetes, then his blood sugar should be 140 or less after two hours. If a non-diabetic such as yourself has a blood sugar greater than or equal to about 140 after two hours then you may have an issue with processing sugar, and will need to see your doctor for diabetes testing. There is no established normal range that we use for non-diabetics at two hours, but most doctors use the 140 cutoff. Please remember the two hour blood sugar test is the most useful. Please see your doctor if you have any further questions or concerns. All the best. ...Read more

Are you overweight?: If you're overweight (and particularly if you have a family history of diabetes) you may be progressing down the road to type 2 diabetes and have high glucoses with a meal and then a rapid correction - which can cause symptoms, but not true hypoglycemia. If you are overweight, get on a life-long diet, exercise and weight loss program or prevent or delay diabetes. ...Read more
